由模型翻译 · 术语统一 · 请对照原文核对关键结论我们提出一种新方法，可从单次多视图场景采集出发，对室内场景进行交互式光照编辑。该方法利用一个生成式、基于图像的光照分解模型，将复杂的室内场景光照分解为构成它的各个光源。这种分解使得能够对单个光源进行独立操控，具体而言可以控制其状态（开/关）、色度与强度。我们进一步引入多视图光照协调，以确保光照分解在所有场景视图上一致地传播。该机制被集成到可重光照的 3D 高斯泼溅表示中，从而提供对各个光源的实时交互控制。实验结果表明，该方法在多种室内场景上实现了高度逼真的光照分解与重光照效果。我们在合成数据集与真实世界数据集上评估了该方法，并与最优技术进行了定量与定性比较。

We present a novel approach for interactive light editing in indoor scenes from a single multi-view scene capture. Our method leverages a generative image-based light decomposition model that factorizes complex indoor scene illumination into its constituent light sources. This factorization enables independent manipulation of individual light sources, specifically allowing control over their state (on/off), chromaticity, and intensity. We further introduce multi-view lighting harmonization to ensure consistent propagation of the lighting decomposition across all scene views. This is integrated into a relightable 3D Gaussian splatting representation, providing real-time interactive control over the individual light sources. Our results demonstrate highly photorealistic lighting decomposition and relighting outcomes across diverse indoor scenes. We evaluate our method on both synthetic and real-world datasets and provide a quantitative and qualitative comparison to state-of-the-art techniques.
